Resumo(s)
INTRODUCTION: Liposarcomas comprise around 15% of soft tissue tumors.
These tumors of mesodermal origin arise as single tumors, present one
histologic type and diverse locations (including the retroperitoneum).
Diagnosis of liposarcomas of retroperitoneum is difficult because of
this unspecific presentation and in 50-100% of the cases there is
recurrence from residual tissue. PRESENTATION OF
CASE: An 86 year old male patient was admitted in 1996 due to a right
and voluminous inguinal hernia. During the herniaplasty, a right
paratesticular tumor was isolated and removed. The histologic exam
revealed a well-differentiated liposarcoma. A CT scan was performed
and a large abdominal mass was detected. The patient underwent a
laparotomy and an incomplete resection of the tumor was achieved.
After the surgery the patient remained asymptomatic during a long
period. Nine years later, the patient underwent another laparotomy
with partial removal of the giant recurrent retroperitoneal
liposarcoma.
CONCLUSION: The purpose of this publication is to report the
recurrence of giant retroperitoneal liposarcoma, which is an unusual
presentation in surgery today. Furthermore, we would like to emphasize
the long-term survival of this patient despite partial resection and
the possibility of performing a re-resection in this type of cases.
